Serial No. aaeeafl i The present invention relatesto-internal combustion engines and inoreparticularly to thecontrol ofthe ignitioncircuit and the throttle valve of the engine. i purvalve ofthe engine in response to the. speed thereof; also it is desirable thatthe ignition circuit be interrupted when the engine is idle. i

An economical manner ofmanufacturing such control isto provide oneengineoperated device for controlling boththe throttle valve and theignitioncircuit. In that type 5 of control there are certaindisadvantages,

for example, the attendant, whileiritendirig to completethe-ignitioncircuit, may movethe control to sucha position as to materially affectthe adjustment of the throttle. valve so" as to I render engine startingdifficult, or, while attemptingto adjust the throttle, the attendantmay'interrupt the ignition circuit.

Gne of the objects of the present invention is to simplify the startingoperation of the v above type of ignition and throttle valve control.Qne manner of carrying out thisobject is to provide an auxiliaryignition control which is segregated, to a certain extent, from thecommon valve and ignition control and which is operable for enginestarting purposes and which may be rendered inoperative after the enginespeed control is effective for maintaining the ignition circuit. I

Further objects and advantages of the 5 present invention will beapparent from the following description, reference being had to theaccompanying drawings, wherein a-preierred form of the present inventionis clearly sh own.
